Compared with the prior art, the utility model beneficial effect who has is: the utility model discloses a first key bush of exempting from, the second exempt from the key bush respectively with first action wheel, second action wheel complex mode, realized to the regulation of the distance between first conveyer belt and the second conveyer belt, its easy and simple to handle, only need to drive epaxial first key bush of exempting from, the second exempt from the key axle carry on the elasticity can, replaced the tradition and used rotary spline and lead screw to adjust the mode of the interval between the conveyer belt, effectively the cost is reduced.

Drawings

The utility model discloses there is following figure:

fig. 1 is a schematic view of the present invention, in which the second mounting seat is hidden.

Detailed Description

As shown in the figures, the conveyor belt adjusting device in the embodiment includes a frame 1, a motor 2 is installed on the frame 1, the motor 2 is in transmission connection with a driving shaft 3, the driving shaft 3 is rotatably installed on the frame 1, a first key-free bushing 4 and a second key-free bushing 5 with adjustable intervals are installed on the driving shaft 3, and the cross sections of the first key-free bushing 4 and the second key-free bushing 5 are in a convex shape. The key-free shaft bushing is a tool connected by friction, converts the fastening force of bolt connection into surface pressure to the inner diameter side surface through a conical surface, does not need time-consuming key processing of a shaft and a connecting shaft part and running-in operation during assembling, and can firmly connect the shaft and the connecting shaft part. The first key-free shaft bushing 4 is provided with a first driving wheel 6, the second key-free shaft bushing 5 is provided with a second driving wheel 7, the frame 1 is further connected with a first driven wheel 8 matched with the first driving wheel 6 and a second driven wheel 9 matched with the second driving wheel 7, the first driving wheel 6 and the first driven wheel 8 are provided with a first conveying belt 10 in a winding manner, and the second driving wheel 7 and the second driven wheel 9 are provided with a second conveying belt 11 in a winding manner.

In this embodiment, in order to facilitate the movement of the first conveyor belt 10 and guide the movement thereof, the first conveyor belt further comprises a first mounting seat 15, the first driven wheel 8 is mounted on a first driven shaft 14, the first driven shaft 14 is rotatably mounted on the first mounting seat 15, the first mounting seat 15 is slidably connected to a sliding rail 13, and the sliding rail 13 is parallel to the driving shaft 3. The first mounting seat 15 is provided with a first through hole through which the first key-free bush 4 can pass.

In this embodiment, in order to facilitate the movement of the second conveyor belt 11 and guide the movement thereof, the second conveyor belt further comprises a second mounting seat, the second driven wheel 9 is mounted on a second driven shaft 12, the second driven shaft 12 is rotatably mounted on the second mounting seat, and the second mounting seat is slidably connected to the slide rail 13. The second mounting seat is provided with a second through hole through which the second key-free bushing 5 can pass.
